Seat Memory: Notes
The seat memory offers the opportunity of storing up to 3 different positions (2 memory presets and "last position used") for every Remote Control used.
This means that if 4 Remote Controls have been assigned to the vehicle, up to 12 different positions can be stored in the individual seat module.
Availability of these 12 positions depends on whether Key Memory is set to "active" or "not active". With Key Memory set to "not active" , only 3 memory positions are available. They are assigned to the vehicle irrelevant of the Remote Control being used.
With Key Memory set to "active" , memory presets stored are assigned to the Remote Control that is currently being identified (memory preset 1 and 2 and the "last position used"). The number of stored positions then becomes 3 X the number of remote controls assigned up to a maximum of 4 (12 positions).
| Remote Control 1 | Remote Control 2 | Remote Control 3 | Remote Control 4 | ||||||||
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
| Key | Mem. 1 | Mem. 2 | Key | Mem. 1 | Mem. 2 | Key | Mem. 1 | Mem. 2 | Key | Mem. 1 | Mem. 2 |
The following components are required for the seat-memory function:
- Memory buttons, driver's and passenger's
- Center Console Control Center (BZM)
- Car Access System (CAS)
- Seat module, driver and passenger (SMFA/SMBF)
- Seat-adjusting motors with a Hall sensor
The SMFA/SMBF requires information from the CAS in order to execute the stored seat positions: Remote Control number and memory buttons (from the BZM).
- The information is sent from the CAS via the K-CAN P to the seat module.
- The seat-adjusting motors are then activated accordingly.
When using the Remote Control to unlock the vehicle, the seat automatically moves to the last position used for that Remote Control.
If an unlocked car is entered and no button of the Remote Control is pressed, the seat moves to the last position stored once the Remote control is identified by the CAS.
At the same time, the CAS sends the same information to:
- The front door modules for the mirror-memory position
- The CIM (Chassis Integration Module) for the steering column memory positions.
